As we are preparing to enable multiplatform support on EXYNOS, we can no longer include mach/*.h or plat/*.h headers from device drivers. The s5p-sss driver was just enabled for EXYNOS when it used to be used only on s5pv210, and it includes two samsung platform specific header files for historic reasons.

2014-05-08crypto: s5p-sss - Look for the next request in the queueNaveen Krishna Chatradhi1-5/+12
Currently, the driver enqueues a request only if the busy bit is false. And every request initiates a dequeue. If 2 requests arrive simultaneously, only one of them will be dequeued. To avoid this senario, we will enqueue the next request irrespective of the system condition (that is what queue is here for). Also schedule at a tasklet immediatly after the current request is done. The tasklet will dequeue the next request in the queue, giving continuous loop. tasklet will exit if there are no requests in the queue.

2014-04-16crypto: nx - Use RCU_INIT_POINTER(x, NULL)Monam Agarwal1-2/+2
This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL) The rcu_assign_pointer() ensures that the initialization of a structure is carried out before storing a pointer to that structure. And in the case of the NULL pointer, there is no structure to initialize. So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL) Signed-off-by: Monam Agarwal <monamagarwal123@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
